The streets around City Hall in Los Angeles, where the largest Occupy encampment to continue in the US was broken up on Tuesday night with 200 arrests, were still closed on Wednesday, according to the KWED newsfix blog .

The eviction was largely peaceful, in sharp contrast with police action to close camps in New York and Oakland.

Officers in riot helmets are seen kicking over tents as they move forward. A line of police officers appear to be encircling the camp as protesters form a circle, chanting. The film pans to a line of officers, one with a bullhorn, warning protesters to "clear the area right now" and to "clear the streets."

At 1.47, we see a shot of an officer holding what looks like a gun, or rubber bullet gun, in both hands, pointing it at the ground.

The film shows an officer with both hands on a gun, pointing off to the right.

A journalist, from behind the camera, can be heard saying: "Esca Milla is pointing his weapon at protesters." The officer then looks up, points his weapon at the sky, then appears to point it at the reporter.

The journalist then shouts: "That's not necessary. You just pointed your weapon directly at me, That's not necessary. I'm worried about it because it's against procedure and it's against code. You're not supposed to do it so keep your finger off the trigger, Thank you. I'm a journalist. I'm allowed to be here."

There are chants of "guns down" from the protesters.

Later, he makes the point that other officers with rubber bullet guns are being "level-headed" unlike "the officer who pointed a gun at me".

Mills said he is within a police cordon of a group of peaceful protesters, including grandmother one-great grandmother, who have given themselves up for arrest.

An officer with a bullhorn gives an eight minute warnings to protesters that if they do not move they will be under arrest.

Some 1,400 officers had been called in for the operation, more than for any event since the Democratic National Convention in 2000, the authorities said.

In Philadelphia, where police raids also took place at Dilworth Plaza on Tuesday night, there were 50 arrests. The eviction came more than two days after a city-imposed deadline for protesters to leave.

Civil affairs captain William Fisher read out the warnings shortly after 1am, telling protesters they would be arrested if they refused to leave, according to WHYY. "The protesters split into two groups, one staying near City Hall, the other taking police on a two hour march through much of Center City," WHYY's report says.
